What I’m looking to do is to develop a real time application on my
700MHz Athalon, targeted to a small 386 board. The application is REAL
TIME, (must have sub 500uS response time to external events) and needs
TCP/IP support. The user will interface with the board via a www
browser.
Target System:
i386EX @ 25MHz
8MB Ram
16MB Disk on Chip (M-systems flash disk)
No Keyboard / Mouse
No Video Hardware, not even basic VGA
2 serial ports
1 parallel port
TTYS1 will be the system console
Ethernet Chip integrated to the board at 0x301 (I know, it’s odd)
Customers will only access the board via TCP/IP. The serial ports are
reserved for my use.
($260 US in quanities of one board)
We purchase the board from t-systems.com. They come with ETLinux, but
I don’t like ETLinux, and I’m looking for an alternative OS to use.
Reworking ETLinux to support real time has been a real pain!
So, will QRTP do it? Linux distros don’t like targeting 386 hardware,
letalone the odd hardware setup on this board.
If I ship 50 units per year, what’s it going to cost me for the
development license (1 programmer), and 50 shipped units per year.
Can’t QNX put the licensing costs on there www site?
BTW: I just finised downloading the QRTP ISO, I’ll be giving it a try
at work in just a few hours. Time to sleep…
Thanks in advance
